Notes. The symbol in Col. 2 refers to the instrument setting: “m” means that a mirror was inserted in the optical path and that therefore only the blue arm was fed; “–” means that the mirror was removed and only the red arm was fed; “d” means that a dichroic was inserted, and that the red arm and the blue arm were fed simulataneously. The horizontal lines define the observations obtained during different observing runs.
Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.
Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.
Initial download of the metrics may take a while.
